FOUNTAIN-BRUSH.

Application filed. February 8, 1916.

To all whom it may concern Be it known that I, CARL A. SUNDSTRAND, acitizen of the United States, residing at Rockford, in the county oflVinnebago and State of Illinois, have invented certain new and usefulImprovements in Fountain- Brushes, of which the following is a specification. I

This invention relates to the general art of fountain brushes, and hasmore particular 7 reference to that class characterized by the provisionof a liquid supplying means attached to the brush head so as to supply aliquid cleaner such as water to the face of the brush during thecleaning operation.

The primary object of my invention is to provide a brush especiallyadapted for cleaning automobiles, vehicles, etc, although suitable fornumerous other-cleaning purposes, and which shallbe of simple design sothat it may be produced at a comparatively low cost.

Another object of my invention is to provide a brush, the handle ofwhich, angularly arranged with respect to the brush head shall serve asa conduit for passage of liquid to the latter and be adjustable so thatthe head and handle may be positioned in different angular relations toallow adaptation of the brush for various cleaning purposes.

My invention also contemplates the provisionin a brush of the characterdescribed, of a cap of improved construction, that is pressed out ofsheet metal so as to enable a simple and effective connection with thebrush head and provide a socket attachment by which the liquid-supplyinghandle may be adjustably secured to the cap.

A further object is to provide a liquidcleaning brush of novelconstruction by which leakage of liquid past the sides of a cap of thebrush is prevented and by which brush heads of various sizes and shapesare interchangeable with the cap.

Referring to the drawings: Figure 1 is a side view of a brush embodyingmy improvements; Fig. 2 is an enlarged longitudinal sectional viewthrough the brush taken on the line 22 of Fig. 3; and Figs. 3 and 4 arecross-sectional views taken on the lines 33 and 4-i, respectively, ofFig. 2.

The brush head designated in general by reference character 5, may be ofsuitable configuration, and while I have shown it merely for purpose ofillustration in the Specification of Letters Patent.

6, suitably secured to the head which is perforated by apertures 7 topermit passage of liquild from the back to the face of the brush heat.

A channel shaped cap designated in general by 8, secured to the back ofthe brush head, provides a liquid chamber to which liquid is supplied soas to pass through the perforated brush head to the bristle facethereof. Fig. 3 shows the inverted U-shape of the cap, the sides 9 ofwhich are engaged in a relatively tight fit in parallel grooves 11formed in the back of the brush headeX- tending lengthwise throughoutthe length thereof. The back of the brush head is shaped so as to engagea greater portion of the interior walls of the sides 9 than the exteriorwalls thereof, that is, referring to Fig. 3, the brush head is formedwithin the sides 9 of the cap with the raised ribs 12 engaging theinterior walls of said sides. Evidently, instead of forming ribs, asshown, the entire portion of the brush back between the sides 9 of thecap may be made of a greater thickness than the outer or marginalportions of the head. Thus, the depth of the grooves 11 may be reducedto a minimum so as to facilitate assembling and interchangeability ofbrush heads, a head comparatively light in weight may be obtained, and ajoint provided between the cap and brush head that will preclude leakageof liquid from the cap past the sides thereof.

At one end of the brush the channelshaped cap is shaped to provide asocket for the reception of an end of a pipe section that constitutes ahandle. The sides 9 at this end of the cap are shaped to provide acylindrical socket 13 and turned inwardly and joined together. so as toprovide a crossportion 14 adapted for preventing escape ofv 7 will beclamped onto a pipe section located in the socket to adjustably securesaid pipe section to the cap. One end of the cap, therefore, is shapedto provide means of attachment for a handle so that the same may be veryeasily and quickly secured to or removed from the cap and adjustedrelatively thereto for a purpose noted hereinafter. At the opposite endof the cap, its channel compartment is closed by the end 21 whichextends nearly to the face of the brush head and is secured thereto bysuitable means, such for instance as a screw eye 22, that also affords aconvenient means for hanging the brush on a hook when not in use. Toremove the cap from the brush head, the screw eye 22 is first removed,and this end of the brush head swung away from the cap on thecrossportion l l as a fulcrum. By the simple converse of thesemovements, the brush head may be secured to the cap, it being evidentthat when the screw is tight ened, the head is secured at both endsagainst removal from the cap.

The handle in the form of a pipe section having an end 23 adapted to besecured in the socket 13 and a major body portion 24 bent angularly withrespect to its end 23 is equipped at its outer end with a suitable handgrasp 25 and is adapted to be connected beyond the end of the same to ahose 26 leading to a source of liquid supply. For ordinary cleaningpurposes water would be supplied through the hose 26 and handle section24 to the cap compartment and thence to the face of the brush. Anoperator grasping the handle 25 may manipulate the brush without comingin actual contact with the cleaning fluid so that the hands are notwetted or soiled in using my improved brush. It is often desirable,because of the location of different surfaces to be cleaned, to adjustthe brush relatively to the handle to permit cleaning in a convenientand effective manner. For this purpose, the thumb nut 19 may be loosenedand the handle rotatably adjusted in connection with the cap so as toposition the brush in a different angular relation to the handlewhereupon the nut 19 would be tightened to secure the brush in suchdesired position.

From the foregoing, it will be apparent that I have provided a liquidcleaning brush exceedingly simple in construction and capable, due toits simple design, of being manufactured at a low cost. It will beevident understood that various changes in details of construction maybe resorted to without departing from the spirit of the invention asexpressed in the appended claims.

I claim:

1. The combination of a brush head the back of which is formed with apair of parallel grooves, a channel-shaped cap having parallel sidesfitting in said grooves and being shaped at one end to provide a sockethaving movable wall portions, a conduit fiti ting in said socket so asto discharge into the chamber formed by the cap and the brush head, thebrush head being perforated to allow passage of liquid from said chamberto the face of the brush, and means for clamping said movable portionsof the cap to the conduit so as to adjustably secure the said pipesection to the cap.

2. The combination of a brush head formed on its back with spacedgrooves and shaped so that the stock of the head is higher along theinner side of the grooves than on the outer side thereof, achannelshaped cap having spaced sides fitting in said grooves, the saidraised portions of the brush head being adapted to prevent liquid frompassing to the exterior of the channel cap through said grooves, thebrush head being perforated so as to connect the cham ber of the capwith the face of the brush, and a conduit connected with the cap forsupplying liquid thereto.

3. The combination of a brush head, a chambered cap secured to the headso that the cap chamber lies adjacent to the back of the brush headwhich is perforated to permit passage of liquid from said chamber to theface of the brush, a conduit serving as a handle and adjustablv securedto the cap so as to discharge into the chamber thereof,'said conduitbeing formed so that its outer portion is in angular relation to itsattached end whereby the handle may be rotatably adjusted in itsconnection with the cap to position the brush head in different angularrelations to the handle.
